IMPROVED LASTlNG-PINCHERS.

Specification forming part Ot' Letters Patent No. 42,!!l5l, datedApril 19, 1864.

To aZZ whom, it may concern:

Be it known that I, ANDREW WEST, of Canton, in the county of Stark and State of Ohio, have invented a certain new and useful Improvement in Pinchers for Lasting the Shanks ot' Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description ot' the same, reference hein g had to the accompanying drawings, which form a part ot this specification, in which- Figure l represents a front view of my improved device when applied to use, the4 lasts and upper leather only being lshown in connection therewith, and they in section. Fig. 2 represents a similar view, the screw-head E heilig raised to permit the jaws to open. rIhe upper ends of the arms C C pass through E. Fig. 3 represents a detached section of some of the parts.

In the drawings, A represents the last, B the upper leather, and uponboth oi'which my device acts, as will now be described.

My improved lasting-pinehers are made up of a spindle, F, upon the upper end of which a left-handed screwthreadis cut.which works through the screw-head E, while the lower end of said spindle has a right-handed screw threadput thereon to work into and through the hinged fulcrum-head D, whose ends pass through slots made in the lower ends of the jaw-arm C C, and are then hinged to the'upper ends of the short jaw-arms C C', which also pass through the same slots in the lower ends ofthe jawarms C G that the fulcrumhead Ddoes. The short jaw-arms C C' are pivoted to the arm's C C at b b, as fully indicated in the drawings. The lower endsof the jaws are grooved out to work into each other, so as to insure a tirm grasp upon the leather, while the upper ends of the arms C are curved out, whereby, when the operator desires to use the instrument he takes hold of cra-nlehandle G and turns the spindle F so as to draw the head E up to the top ofthe spindle, when, by grasping the upper ends ot' arms (l C, the jaws will open freely, and the pinchers are now placed astride the last, the upper leather on each side being placed in the jaws, after which the crank is turned so as to force down the head E, thereby causing the jaws to close firmly upon the leather, while the lower end ot' the spindle F, as soon as it comes upon the inner sole (which should tirst loe placed upon the last, although not shown in the drawings) raises the pinchers and upper leather over the inner sole, and at the same time draws the leatherrmly and tight about the shank, where it can be fastened by pegs or nails, and the pinchers then removed by simply turning handle G in'an opposite direction so as to raise head E, as seen in Fig. 2. The greater the force exerted in lasting the shanks of boots and shoes the iirmerwill thejaws grasp the leather.

Having described my improved pinchers for lasting the shanks ot' boots and shoes, what I claim and desire to secure by Letters Patent as a new article of manufacture, is-

A pair of looot and shoe lasting-pinchers, constructed substantially as above described and as shown in the accompanying drawings.
